TIPS is the Eurosystem's instant-payment settlement service, operated by the European Central Bank on behalf of the four central banks (Banca d'Italia, Banque de France, Bundesbank, Banco de España). It is the central-bank-money settlement layer that underpins most SEPA SCT Inst flows — the rail beneath the rail.
Each SCT Inst flows through one of two layers: TIPS (Eurosystem) or RT1 (EBA Clearing's commercial-bank-money instant rail). The customer-facing pain.001 is identical for both; the choice is per-PSP and is made at the inter-bank layer. TIPS is the dominant settlement layer for most EU corridors today.
Settlement at TIPS is on commercial-bank reserve accounts held at the relevant NCB, with full 24/7 availability. The per-transaction cap matches the SCT Inst scheme limits. Settlement finality is achieved within seconds with no T+1 deferral.
TIPS supports non-euro settlement on opt-in: Sveriges Riksbank (SEK) joined in 2024, Danmarks Nationalbank (DKK) joined 2025. This is the Eurosystem's answer to fragmented non-euro instant rails inside the EU.
Not implemented in iso-compliant directly — TIPS is a settlement layer, not a customer surface. The relevance for documentation purposes is that an SCT Inst sent via iso-compliant's pain.001 emitter will be cleared through TIPS or RT1 depending on the originator's PSP, with no application-side visibility into which.
